It mainly controls Alopecurus aequalis, Digitaria sanguinalis, Echinochloa crus-galli, Setaria viridis, Lolium perenne, Chenopodium album, Polygonum, Stellaria media, etc., and is safe for subsequent crops.
2. Dual 72% emulsifiable concentrate, 0.1-0.15 liters per mu mixed with 450-600 liters of water, applied after land preparation but before planting or immediately after planting. Under dry conditions, it should be shallowly incorporated into the soil. It mainly controls Echinochloa crus-galli, Digitaria sanguinalis, Setaria glauca, Eleusine indica, Poa annua, Eragrostis, Brachiaria, Lolium perenne, Chloris virgata, Brassica juncea, Lamium amplexicaule, Cyperus esculentus, Amethystea caerulea, Cuscuta, etc., and is safe for subsequent crops.
3. Devrinol (napropamide, napropamide) 50% wettable powder, 100-150 grams per mu, mixed with 600-750 liters of water, applied before planting sweet potatoes or immediately after planting; under dry conditions, irrigation may be applied after treatment. It mainly controls Avena fatua, Echinochloa crus-galli, Digitaria sanguinalis, Setaria viridis, Alopecurus aequalis, Poa annua, Eleusine indica, Chenopodium album, Galium aparine, Stellaria media, etc. When the application rate of 50% Devrinol is within 150 grams per mu, it is safe for subsequent crops. If this rate is exceeded, phytotoxicity may occur in the next crop of gramineous crops such as rice, wheat, barley, sorghum, and corn. Other herbicides include trifluralin, Goal, haloxyfop-P-methyl, Harness, fluazifop-P-butyl, quizalofop-P-ethyl, oxadiazon, sethoxydim, clethodim, and Whip.
